The Danes, playing at their first World Cup since 2007, thought they had scored early against Haiti in front of just under 18,000 in Perth but it was ruled out after a VAR review found Simone Boye was just off-side.

Denmark made their early pressure count when Haiti conceded a penalty -- their third at this World Cup -- for handball.

Skipper Pernille Harder scored from the spot.

Haiti woke up and had a golden opportunity just before the half-hour, but captain Nerilia Mondesir's effort was weak and easily saved by goalkeeper Lene Christensen.

Haiti refused to go quietly in the second half and Melchie Dumornay headed weakly at Christensen from close range as they chased a first World Cup goal.

Denmark sealed the deal deep in stoppage time through Sanne Troelsgaard.
